    I don't believe all pins are supposed to be there. A good chance it's your elog. I'd try it on another truck to make sure it works.

    There's nothing wrong with the DIAG port. All pins necessary are there.

    If you're questioning it functioning, then get out your multi meter.

    What voltage do you get with A-B? What do you get with A-C? What do you get with A-D?...

    by multimeter you can check only voltages not actual readiness of data transmission
